一个基于笔划和多重绘制的树木生成模型及其实现

A Tree Creating Model Based on Stroke and Multi-Pass and Its Implementation

针对以虚拟景物或艺术作品生成为目的的非真实感图形绘制,提出了一个基于笔划与多重绘制的树木生成模型,该模型能使绘制者在多重绘制中选择合适的树叶笔刷模型以及它的参数,反复优化笔刷的粘贴位置直到获得满意的树木形态,从而绘制出具有明显手绘国画风格的作品.方法对运用笔划绘制技术实现非真实感艺术作品创作也是一种很好的尝试.

In order to generate virtual scene or work of art by non-photorealistic graphics rendering, a tree-creating model based on stroke and multi-pass rendering is proposed. The model enables painters to select an appropriate paintbrush model of leaf and its parameters in multi-pass rendering and to optimize repeatedly the paintbrush stick- up position till the satisfactory tree morphology is obtained, thus to render painting works with distinct hand-painted Chinese painting style. This method is a good try in creating non-photorealistic artistic works by using stroke render-ing technique.
